Aerial Lengths for perfect tx/rx

[MINISTOCK23]

I've recently run into some problems with transmitter and reciever ranges, I practice near a electric substation and it seems to effect the cars range.
I've checked out frequency length matched aerial charts and if I'm running 27.195Mhz (Green/Band 5) I need a 10.5 Meter aerial.
Can anybody tell me if this is the case and can I use a coiled aerial? (A 1:12 scale car would look stupid with a mast that big)
:confused:

Well the higher out of the body the more likely it is that you will get cleaner reception. However this is more dependant on the length of the antenna then it is how high it sticks out. You can coil excess length of the antenna wire at the base of the antenna tube or roll over antenna but make sure you don't coil the wire around itself. Typically a 1/12th runs a roll over antenna which is a solid fiberglass antenna pole that the antenna wire wraps around. This is to get the car back on it's wheels when it flips over. Usually it's about 10" tall (rough guess). DO NOT cut the antenna wire to this length. Reguardless how tall you make your antenna mast running near an electric substation is very likely to give you problems so your going to need to be very careful with your car's wiring setup. Keep the power wires that go to the battery and the motor as far away from the antenna as possible. Make sure your running 3 capacitors on the motor. Maybe even turn your reciever on it's side.

Thanks for the advice.
I wasn't talking about height I of aerials I was talking how long the aerial should be in relation to the length of the radio wave.
Since posting this I have found out the lots of R/C tx and rx equipment has phantom lengths on the aerials ie. micro chips trick the tx into thinking the aerial is the correct length...
...its all too confusing!!!

Reciever antenna wires are cut to the length they need to be for their frequency by the manufactuer. Altering that length will cause your range to be reduced and glitching to occur.
